Abstract

There is inter alia disclosed an apparatus for spatial audio encoding comprising: means for transforming a multichannel audio signal into time frequency signals and analyse the time frequency signals to obtain at least two spherical direction vectors, wherein a first spherical direction vector is associated with a first frequency band of the time frequency signals and a second spherical direction vector is associated with a second frequency band of the time frequency signals; determining an energy of the first frequency band and an energy of the second frequency band; and merging the first spherical direction vector and the second spherical direction vector into a merged spherical direction vector
